  9. What Is LabVIEW MathScript? Powerful textual programming for signal processing, analysis, and math • More than 650 built-in functions • Reuse many of your m-file scripts created with The MathWorks, Inc. MATLAB® and others • Based on original math from NI MATRIXx A native LabVIEW solution • Interactive and programmatic interfaces • Does not require third-party software MATLAB® is a registered trademark of The MathWorks, Inc. All other trademarks are the property of their respective owners.

  10. MathScript Features 2

  15. The MathScript Window : History Tab 5-d Right Click to Clear History

  16. MathScript Node 5-e • Embed MathScripts into LabVIEW code on the block diagram • Populate with m-file script text • Type m-file scripts directly into the node • Import from files • Create inputs/outputs on node edges • MathScript compiles script when run • Unlike MATLAB® script nodes, MathScript script nodes do not require third-party software MathScript Node MATLAB® is a registered trademark of The MathWorks, Inc

  17. MathScript Node 5-f m-Script MathScript Node Right-Click Menu

  18. Programmatic Math with the MathScript Node • Combine graphical system design with textual math • Deploy with LabVIEW graphical programming • Implement equations and algorithms with text

  19. Goal: Multiple Programming Approaches Freedom to choose the best approach Reuse your existing code Add interactive user interfaces to your algorithms Integrate math with real-world I/O and instrument control

  20. Demo: MathScript

  21. Working with Graphical and Textual Approaches in LabVIEW • Always consider both • Prototype and instrument your math algorithms • Use LabVIEW features through graphical programming • Take a mixed approach to combine graphical and textual benefits • Work within a single environment to simplify and reduce cost • Reuse your existing m-files

  22. Major Features in LabVIEW 8.20 • MathScript • Object-Oriented Programming • 3D Picture Control • DLL Import Wizard • TDM Streaming • …. ni.com/labview/upgrade

  23. LabVIEW Object-Oriented Programming Parent Class Classes and objects Encapsulation Child Class Inheritance For power programmers and large-scale application development

  24. Demo: Object-Oriented Programming

  25. Major Features in LabVIEW 8.20 • MathScript • Object-Oriented Programming • 3D Picture Control • DLL Import Wizard • TDM Streaming • …. ni.com/labview/upgrade

  26. History of 3D in LabVIEW • LabVIEW 5.1: • First 3D Graphs available • ComponentWorks controls based on ActiveX • LabVIEW 7.1: • First 3D Picture Control software • Separate download • No technical support offered

  27. 3D Picture Control • Create 3D scenes using picture control VIs • Control object motion, size, and color using OpenGL • Import objects from design tools (VRML, STL, ASE ) Demo

  28. Introduction to API Geometries Box, Cone, Cylinder, Height Map, Mesh or Sphere Object Create or Find object Transformations Translate, Rotate or Scale objects Helpers Color, Light, Window, Texture, etc. File Loading Import ASE, STL or VRML files Further functionality available through Property and Invoke Nodes How Does it Work?
